Multi-walled carbon nanotubes (MWNTs) were pretreated ultrasonically in 36% HCl and then functionalized in 2.2 mol/L HNO₃,and then dispersed in N,N-dimethylformamide (DMF).The MWNTs modified glassy carbon electrode (MWNTs/GCE) was prepared by dropping 2 μL of MWNTs (0.1 g/L) in DMF on the surface of a glassy carbon electrode.The MWNTs/GCE can catalyze the electro-oxidation of ascorbic acid (AA).On the cyclic voltammogram,AA has two well-separated oxiditive peaks in pH=4.0 B-R buffer solution at 0.187 V and 0.452 V (vs.SCE),respectively,the mechanism of which can be illustrated according to the molecular structure of AA and the electrocatalytic properties of the carboxylic acid group-functionalized MWNTs.The electro-oxidation of AA at MWNTs/GCE is an adsorption-controlled irreversible electrode process.The surface concentration of AA on the electrode was calculated to be 1.02×10^-9 mol/cm²,and the standard rate constants of the electrode reactions of the two oxidative peaks of AA were calculated to be 1.03×10^-2 s^-1 and 3.94×10^-3 s^-1,respectively.AA was satisfactorily detected by using differential pulse voltammetry with a linear range from 5.0×10^-7 mol/L to 5.0×10^-2 mol/L and a detection limit of 5.0×10^-8 mol/L (S/N=3).
